Summary
This case study highlights vasculitis as a rare but severe complication of relapsing polychondritis (RPC). Prompt treatment with methylprednisolone led to symptom regression, emphasizing the need for renal screening in RPC patients.
Area of Science:
- Rheumatology
- Nephrology
- Immunology
Background:
- Relapsing polychondritis (RPC) is a rare systemic autoimmune disease.
- Vasculitis is a known complication of RPC, affecting approximately 25% of patients.
- Clinical manifestations often include cutaneous, neurologic, and renal involvement, particularly in elderly individuals.
Observation:
- A 78-year-old male with a history of RPC presented with purpura, fever, arthralgias, delirium, and nephrotic syndrome.
- Renal biopsy revealed diffuse endo- and extracapillary proliferative glomerulonephritis with mesangial IgA deposits.
- Symptoms significantly improved following pulse intravenous methylprednisolone therapy.
Findings:
- The patient's presentation exemplifies the complex interplay between relapsing polychondritis and systemic vasculitis.
- The presence of mesangial IgA deposits in the renal biopsy is an uncommon finding in RPC-associated vasculitis.
- Effective management with high-dose corticosteroids demonstrated a positive therapeutic response.
Implications:
- Systemic vasculitis represents a severe manifestation of relapsing polychondritis.
- Renal involvement in RPC signifies a serious disease course.
- Systematic renal complication screening is crucial for patients diagnosed with relapsing polychondritis to identify severe forms early.
